Readme

chosen
chosen is a node module to make multiple-choice questions easy on CLIs.

Install

npm install chosen

Use

var choose = require("chosen").choose;

console.log("What is your favorite language?");
choose(
    ["English", "Klingon", "Malbolge"],
    function(answer, index) {
        console.log("I like " + answer + ", too!");
    },
    {} // options
);

Styles

You can feed any of the following options:
  • style: one of [">", "gray", "indent"], or an object {normal: <function>, chosen: <function>}, where the functions return a formatted version of their inputs

Interaction

chosen interaction was—ahem—chosen to be intuitive:
  • <enter> and <space> select the current choice
  • <esc> and <^C> to escape (sends null)
  • (up arrow, down arrow), (k,j) (vim!),(q, a), and (p, l) for scrolling up/down (any other key defaults to "down")
